Novel method of electrodeposition coating.

摘要

A method of electrodeposition coating which permits low-temperature curing and comprises electrodepositing a water-base electrodeposition coating composition comprising an ionic group-containing resin and a crosslinking agent as vehicles on an article to be coated and then heating the coated article to form a cured coated film, wherein the ionic group-containing resin contains a hydroxyl group and the crosslinking agent contains at least two alkoxysilane groups and optionally hydroxysilane groups per molecule, and said resin can be cured by condensation reaction between said functional groups and the hydroxyl groups.
